Definitions
- HDC Hill Descent Control
- the engine operating conditions change, among other things, in such a way that the engine changes from idling behavior (unloaded run) to normal operation (loaded run) by the engine driving the vehicle, so that the engine output power is largely and particularly defined to drive the Vehicle is used.
- the speed depends on the position of the accelerator pedal, the gear engaged, the engine drag torque and the gradient (slope of the road).
- the engine drag torque is often not sufficient to allow a controlled descent.
- Such vehicles are usually equipped with an anti-lock braking system (ABS) and a traction control system (ASR).
- ABS anti-lock braking system
- ASR traction control system
- the already existing assemblies such as electronics, wheel speed sensors, Longitudinal acceleration sensors, solenoid control valves, motor-pump units etc. are also used to carry out the above-mentioned speed control.
- the known assemblies relieve the driver on downhill gradients of having to constantly press the brake pedal. A constant speed is maintained even with different road inclinations.
- Knowing the direction of travel is particularly important for control systems such as the HDC in off-road use.
- the target speed can be specified depending on the direction of travel (slower backwards) or the ABS function can be designed depending on the direction (select low). It is particularly important to receive valid direction information as soon as possible after starting the vehicle. Early directional information is required, especially when rolling with high acceleration (rolling back on a steep slope), since braking intervention by the HDC must take place very soon (at 2-3km / h) if you want to avoid overshooting the speed. On the other hand, it is a rather smooth start (flat slope) not critical if the
- Direction information is available late or shows the wrong direction for a limited time.
- the invention is based on the object of specifying a method and a device of the type mentioned at the outset by means of which a direction of travel detection, in particular on a mountain, can be detected in all driving situations.
- the detection of the direction of travel is determined as a function of internal and / or external vehicle variables, such as the engine speed, the engine torque, the accelerator pedal position, the gear engaged, the clutch state, the turning behavior of the wheels, the longitudinal acceleration, the road inclination, by correlating at least two vehicle variables , the selection of the variables to be correlated taking place in accordance with a status determination of the vehicle sizes and / or if the vehicle sizes meet certain conditions with regard to their time profiles.
- vehicle variables such as the engine speed, the engine torque, the accelerator pedal position, the gear engaged, the clutch state, the turning behavior of the wheels, the longitudinal acceleration, the road inclination
- the status determination of the vehicle sizes aims at speed-determined conditions of the vehicle, such as vehicle standing, vehicle is driven, vehicle is in a load-free run (free rolling) or in one Uphill-braking operation (HDC mode of operation) and / or on the continuation of these conditions for a certain period of time, such as a short standstill of the vehicle, a long standstill of the vehicle.
- speed-determined conditions of the vehicle such as vehicle standing, vehicle is driven, vehicle is in a load-free run (free rolling) or in one Uphill-braking operation (HDC mode of operation) and / or on the continuation of these conditions for a certain period of time, such as a short standstill of the vehicle, a long standstill of the vehicle.
- a further increase in the reliability of the determination of the direction of travel can be achieved by selecting a strategy for recognizing the direction of travel of the vehicle from at least two different strategies depending on the status of the vehicle sizes, which represents the priority of the direction of travel detection determined from the correlated conditions.
- the status can be an identification of the respective strategy, a defined sequence of the strategy to be carried out or a prioritization of the respective strategy that is dependent on variable criteria, preferably on the length of time and / or the vehicle state variables.
- Gear is engaged, determined. If these conditions are met, there is a forward drive when a forward gear (VGang) is engaged and a reverse drive when a reverse gear (RGang) is engaged.
- VGang forward gear
- RGang reverse gear
- the gear engaged is determined via a switch which is actuated when the gear is engaged.
- the clutch can also be closed via a Switch signal sensed or model-based, via the
- the driving resistance can simply include the downhill drive or additionally a speed-dependent one
- Driving resistance vehicle mass *
- Driving resistance vehicle mass * ⁇ a ⁇ + resistance depending on
- the direction of travel detection is carried out according to a second or further strategy if at least one of the
- the second strategy it is determined as an input condition whether the vehicle stands for a certain minimum time (for example 500 ms).
- the standstill is recognized by carrying out a first comparison of a quantity describing the speed of the vehicle (VFzg) and a characteristic threshold value (FzgS) for the quantity describing the speed of the vehicle.
- a second comparison is carried out, a difference, which is formed from a filtered aFilt and an unfiltered longitudinal acceleration signal ( ⁇ ), being compared with a characteristic threshold value aSl for a longitudinal acceleration signal.
- ⁇ unfiltered longitudinal acceleration signal
- the second comparison it is determined whether the longitudinal acceleration signal lies in a defined band, ie is essentially stationary, that is, low-pass filtered and unfiltered signals differ from one another by no more than a threshold value (eg 0.015 g) for a certain time (eg 500 ms). Based on these two comparisons, preferably if the condition VFzg ⁇ VFzgS is fulfilled and the condition ⁇ a S was previously fulfilled over a predefined time, the vehicle is started up or rolled on using a third comparison.
- a threshold value eg 0.015 g
- the wheels turn also indicate that the vehicle is starting or coasting, by exceeding a speed threshold VFzgS of the vehicle speed VFzgS, the start detection is confirmed, otherwise the vehicle will move forward when the vehicle is in forward gear Forward driving direction) and with reverse gear engaged (reverse gear) on reverse driving (reverse driving direction), since there is no better knowledge.
- the vehicle speed is from the Derived rotational behavior of the wheels.
- the direction of travel detection of the vehicle is carried out according to a third strategy.
- the direction of travel is determined depending on the last lane gradient saved before standstill (condition VFgz ⁇ VFgzS not yet fulfilled). This road gradient is calculated before standstill based on the following direction-dependent relationship:
- a vehicle acceleration becomes from a quantity describing the wheel speeds
- This vehicle acceleration is characterized by a characteristic threshold value a (wheel) S for the
- Wheel speeds of the vehicle determined vehicle acceleration compared in terms of amount and determined the direction of travel from an unfiltered longitudinal acceleration signal a according to the comparison.
- Influencing the service brake is kept constant or limited (HDC operation) and the model-based brake pressure is> a corresponding threshold value, it is recognized when driving backwards if there is a positive longitudinal acceleration signal for a predetermined minimum time, and when driving for a predetermined minimum time when forward driving is detected negative longitudinal acceleration signal is present.
- a generic device for detecting the direction of travel of a vehicle is designed in such a way that the device recognizes means for detecting the direction of travel as a function of internal and / or external vehicle variables, such as the accelerator pedal position, the engine speed, the engine torque, the gear engaged, the clutch state, and the rotational behavior of the vehicle Wheels, the longitudinal acceleration, the road inclination, and also evaluation means for correlating at least two variables and for selecting the variables to be correlated according to a status determination of the vehicle sizes and / or if the vehicle sizes meet certain conditions with regard to their time profiles.

- a cruise control function (automatic speed setting) is implemented using the determined direction of travel.
- the determined direction of travel can, however, also be used for other purposes.

- Block 510 determines whether or not there is a reverse drive.
- the road gradient is calculated and saved outside the first or second strategy (i.e. while driving) according to the following relationship:
- a query is made in block 540 as to whether there is a stored positive slope signal. This is because if reverse travel is determined (block 550), if there is no positive incline signal, the stored negative incline signal is queried in block 560 and, if present, forward travel (block 570) is determined.
- Longitudinal acceleration signal 630, 635 is detected on forward travel.
- the case that the motor works against the brake, and thus e.g. in a vehicle with an automatic transmission, the target speed drops below idle speed, can be excluded by minimum thresholds with longitudinal acceleration and / or model brake pressure.
